The utility model discloses a connecting structure for leveling a wall surface, which comprises a wall surface bearing member, a connecting frame and a plurality of purlines with adjustable positions, the connecting frame is connected with the wall surface bearing member, and the purlines are connected with the connecting frame through self-tapping screws; by means of the electromagnetic supporting block, the first leveling auxiliary assembly and the second leveling auxiliary assembly, a plurality of purlines can be located on the same vertical plane under the condition that the wall face is subjected to construction errors, the leveling precision of the wall face is guaranteed, and particularly, the position-adjustable purlines are additionally arranged on the wall face bearing component, so that the wall face bearing component is more accurate in leveling. The first datum plates of the auxiliary leveling assemblies arranged on the same plane serve as datum points, and purlines are adjusted and supported by means of wedge-shaped electromagnetic supporting blocks so that the purlines can be located on the same plane.

A clutch driven disc heat treatment processing tool belongs to the clutch processing technology field. The purpose of the present invention is a clutch driven disc heat treatment processing tool that can directly perform driven disc quenching and leveling at the same time. The present invention includes an upper hydraulic mechanism and a lower hydraulic mechanism. The advantage of the present invention is that profiling and quenching are performed simultaneously, which ensures the flatness accuracy of the workpiece, and can prevent the parts from being deformed under high temperature and high pressure conditions while meeting the flatness requirements. The deformation amount of the parts is guaranteed to ensure the flatness of the driven disc, thereby reducing the high-temperature leveling process. During the quenching and cooling process of the parts, the thermal balance flow of the quenching oil can be adjusted to ensure that the oil amount is sufficient during quenching, and the parts can obtain a good quenching effect.
